By selecting the next higher pulse number from the above table (1 litre per pulse) the user will make
sure that the pulse output frequency will not exceed (for the specified Q
max
of 150 m
3
/hour) the value of
100Hz and, at the same time, verify the selection of the pulse length (5ms). The user may choose the
V
values other than those from the basic selection in the above table, e.g. 0,5 litres/pulse.

Shielded cables must be used to connect the output signals.
The shield is only connected on one side, namely the PE terminal located on the terminal board.
5.6.2 Current output 4 to 20mA
Functions and parameters
•
Passive current output electrically insulated from the ground and other inputs and outputs
•
